Description

(E)-6,10-Dimethylundeca-5,9-Dien-2-Yl Acetate is a high-purity fragrance and flavor intermediate known for its characteristic floral and fruity aroma profile. This compound is valued for its role as a key building block in the synthesis of complex aroma chemicals and as a direct fragrance ingredient. It is essential for manufacturers in the flavor and fragrance (F&F), cosmetic, and personal care industries seeking to create sophisticated, natural-smelling scent compositions.

Application

• Fragrance Formulation: A key component in fine perfumery for creating floral (rose, lily) and fruity nuances in high-end perfumes, colognes, and eau de toilettes.
• Flavor Enhancement: Used as a flavoring agent or intermediate to impart fruity and sweet notes in food products, beverages, and confectionery.
• Cosmetic & Personal Care: Incorporated into scented lotions, soaps, shampoos, and other personal care products for its stable and pleasant aroma.
• Aroma Chemical Synthesis: Serves as a critical chiral intermediate or starting material in the organic synthesis of more complex terpenoid fragrance molecules.
• Household Products: Used in air fresheners, fabric softeners, and cleaning products to provide a long-lasting, fresh scent.
• Industrial Deodorants: Applied in masking undesirable odors in industrial settings or consumer goods.

Quality Control

Our (E)-6,10-Dimethylundeca-5,9-Dien-2-Yl Acetate is produced under strict quality management systems. Each batch is analyzed to ensure it meets stringent specifications for identity, purity, and olfactory profile, suitable for flavor and fragrance applications. Certificates of Analysis (COA) detailing GC purity, optical rotation, and organoleptic properties are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at 15-25°C. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize degradation. Keep away from heat, sparks, and open flame.
